Who We Are

Metal production accounts for 10% of all human generated greenhouse gases. One of the most effective paths to reducing those emissions is by maximizing our recovery of metals through recycling, which requires a fraction of the energy compared to mining.

VALIS’ mission is to lead a circular economy powered by data that protects the planet, its resources, and its inhabitants. We are a B2B SaaS company that provides next generation technology to metal recyclers enabling them to optimize their operations by making data-driven decisions. We’re focused on integrating and improving processes along the entire recycling chain, so the materials of yesterday are properly recovered to meet the demands of tomorrow.

We’re an early-stage company, backed by leading climate-tech VC’s, looking to bring on new team members that can help us build VALIS and transform the industry. We lead with authenticity, boldness, passion, and empathy focused on creating a more sustainable future. A career at VALIS is one where you’ll be empowered to expand your technical and leadership abilities while having a positive impact on the world.
